Blooms of σ0 in the TOPEX Radar Altimeter Data
(American Meteorological Society, 2004)Data from satellite altimeters are often degraded by the occurrence of unrealistically high radar return cross sections, which indicate a breakdown of the rough surface scattering model used to interpret these measurements ... -
Wind Stress Curl and Wind Stress Divergence Biases from Rain Effects on QSCAT Surface Wind Retrievals
(American Meteorological Society, 2004)Surface vector wind datasets from scatterometers provide essential high-resolution surface forcing information for analyses and models of global atmosphere?ocean processes affecting weather and climate. The importance of ... -
An Analytical Model of Heating Errors in Marine Air Temperatures from Ships
(American Meteorological Society, 2004)Marine air temperature reports from ships can contain significant biases due to the solar heating of the instruments and their surroundings. However, there have been very few attempts to derive corrections. The biases can ... -
Small-Scale Rain Nonuniformity and Its Effect on Evaluation of Nonuniform Beam-Filling Error for Spaceborne Radar Rain Measurement
(American Meteorological Society, 2004)An observational method has been proposed to sample radar echo with high range resolutions using a ground-based meteorological radar. Utilizing this method, the rainfall echo data with a high range resolution of 125 m was ... -
Observations of Quasi-Symmetric Echo Patterns in Clear Air with the CSU–CHILL Polarimetric Radar
(American Meteorological Society, 2004)On a few occasions during the summer and fall of 2002, and again in the fall of 2003, the Colorado State University (CSU)?University of Chicago?Illinois State Water Survey (CHILL) S-band polarimetric Doppler radar observed ... -
A New Turbulence Microbarometer and Its Evaluation Using the Budget of Horizontal Heat Flux
(American Meteorological Society, 2004)The construction, calibration, and application of a microbarometer that is capable of accurately measuring turbulence pressure fluctuations is described. The microbarometer consists of a quad-disk pressure probe and a ... -
Complex Quality Assurance of Historical Hourly Surface Airways Meteorological Data
(American Meteorological Society, 2004)A new complex quality assurance (QA) procedure is developed for historical hourly surface airways meteorological data, recently digitized in a U.S. government?sponsored effort that extends the digital period of record back ... -
Daytime Multilayered Cloud Detection Using Multispectral Imager Data
(American Meteorological Society, 2004)This study reports on recent progress toward the daytime detection of multilayered clouds in satellite multispectral data, specifically for the case of optically thin cirrus overlying lower-level water clouds. The technique ... -
Portable Automated Mesonet II
(American Meteorological Society, 1986)The Portable Automated Mesonet II (PAM II) system was developed by NCAR to provide surface mesoscale data for the research needs of the atmospheric science community. The PAM system has 60 remote stations with planned ... -
Unexplained Discontinuity in the U.S. Radiosonde Temperature Data. Part II: Stratosphere
(American Meteorological Society, 2004)The second part of this two-part article discusses the differences between observations taken at 0000 and 1200 UTC, particularly in the stratosphere, by the Vaisala RS80-57H radiosondes that are integrated within the ... -
Evaluation of the Accuracy of a Ship-Mounted, Bottom-Tracking ADCP in a Near-Shore Coastal Flow
(American Meteorological Society, 2004)The accuracy of an acoustic Doppler current profiler (ADCP) used with an internal bottom-tracking system is considered. The boat speed measured using bottom tracking is extremely accurate, comparable to the speeds measured ... -
Observations of Transport Variability in the Baltic Sea by Parasitic Use of a Fiber-Optic Cable
(American Meteorological Society, 2004)Transports between the Swedish mainland and the island of Gotland were studied by means of motionally induced voltages. The copper mantle of an existent fiber-optic telecommunications cable was grounded on Gotland, and the ... -
A Two-Spot Sensor for Measurement of Dissipation by Means of Laser-Doppler Velocimetry
(American Meteorological Society, 2004)An estimate of the dissipation rate for mechanical energy in a turbulent flow can be obtained by computing the variance of the temporal derivative of the fluid velocity measured at a single point. This technique is not ... -
An Example of North Atlantic Deep-Ocean Swell Impacting Ascension and St. Helena Islands in the Central South Atlantic
(American Meteorological Society, 2004)During 1999, the dataloggers of the pressure transducer?based tide gauges at Ascension and St. Helena Islands were upgraded in order to enable the monitoring of wave conditions in addition to the measurement of still water ... -
Air–Sea Heat Flux Measurements from Nearly Neutrally Buoyant Floats
(American Meteorological Society, 2004)The ability of neutrally buoyant, high-drag floats to measure the air?sea heat flux from within the turbulent oceanic boundary layer is investigated using float data from four different winter and fall float deployments. ... -
Forecasting the Coastal Ocean: Resolution, Tide, and Operational Data in the South Atlantic Bight
(American Meteorological Society, 2004)This paper addresses shelf-scale simulation with dominant open-water boundary conditions obtained by inversion of interior data. Important, established operational data streams are located along the shore of the study area, ... -
An Evaluation of Depth Resolution Requirements for Optical Profiling in Coastal Waters
(American Meteorological Society, 2004)Wave perturbations induce uncertainties in subsurface quantities determined from the extrapolation of optical measurements taken at different depths. An analysis of these uncertainties was made using data collected in the ... -
